The present invention relates generally to an agricultural apparatus and Vparticularly to a ground packer and has for its prime object to provide an apparatus of this nature comprising a plurality of connected sections, each section including a plurality of blades which maybe adjusted. v

A further very important object of the invention resides 1n the provision of an apparatus of this nature which is exceedingly simple in its construction, strong and durable, inexpensive to manufacture, easy to adjust and thoroughly eliicient and reliable in use and operation.

With the above and numerous other objects in view as will 4appear as the description proceeds, the invention resides in certain novel features of construction, and in the ccmbination and arrangement of parts as will be hereinafter more fully described and claimed.

` In the drawing:

Figure 1 is a top plan view of the apparatus embodying the features of my invention,

Figure 2 is an enlarged detail side elevation of the front end o the apparatus,

Figure 3 is an enlarged detail section through one section of the apparatus,

Figure 4 is a sectional view taken substantially on the line L1--4- of Figure 3, and

Figure 5 is a top plan view of one of the packer blades attached to its shaft.

Referring to the drawing in detail it will be seen that the numeral 5 denotes a trans versely disposed draw bar at the front end of the apparatus which is provided with a plurality of hook bolts 6 extending rearwardly therefrom. l

Two rows of sections extend rearwardly from the draw bar 5 andeach section ccmprises a U-shaped hood 7 of elongated construction with the bight portions disposed forwardly and .the upper leg slightly wider than the lower leg as is clearly illustrated in Figure 3. Bearing blocks 8 aremounted in the ends of the hood 7. Notched segments 9 are mounted on the upper legs at the ends of the hoods'by means of screws 10 which also hold the blocks 8 in place.

Screws 11 are used to fasten the blocks to 50 the bottom leg 'of the hood. A shaft 12 is rockable in the blocks 8 and have levers 14 secured to the ends thereof and rising therefrom. Hook plates 15 are` fixed-in the ends of the hood to the outer sides of the block and have eyes 16 at their forward ends' and vhooks 55 17 atv their rear ends.

Links 18 are enga ed inthe eyes 16 and are adapted to engage' ooks'17 except the two forwardmost sections and their links engage the hooks 6. 4U-shaped members 19 are fixed e0 by means of rivets 20 or the like circumjacent the shaft 12 and the ends terminate rearward- 1y thereof and have brackets 22 rockable t erebetween by pins 23.

Packer blades 24 are anchored by means e5 offbolts 25 in the brackets 22. Obviously by rocking the levers 14 the packer blades may be swung upwardly or downwardly to adjust their digging depth. Detent structures 26 are mounted on the levers14 for coo eration 70 with the notched se ments 9 so as to old the liker blades in di erent adjusted positions.

is packing apparatus works on a swivel which always pulls straight through the ground. y

The packer blades work at an adjustable depth in the ground. This apparatus cuts the air spaces out of thevgron pulverizes and packs the ground in one operation and thereby retains the moisture and keeps the roots of the grain in good growing condition vto cause an increased yield.

It is thought that the construction, utility,

operation and advantages of this invention will now be quite apparent to those skilled in this art without a more detailed description thereof. v 'l The present embodiment of the invention has been disclosed in considerable detail merely for the-purposes of exem lification since in actual practice it attains t e features of advantage enumerated as desirable in the statement of the invention and the above description.

It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.
